Hi All,
B&C offer a couple different capacitors, 10,000uF (at)50VDC and 47,000uF
(at)16VDC. Is one of these appropriate for use on the Rotax alternator?
Thanks, Kevin

This is not a really critical capacitor with
respect to value but 16v is bit low for
a rating. 25V or more is the target. Furhter,
the "rule of thumb" for sizing is 1,000 uF per
amp of alternator output so the 10KuF/50v is
pretty good for the SD-8. Your system would
be better served by 20KuF/25V or larger.
